ResumoUpogebia quddusiae n. sp. Material and measurements. ? Pasni, at 110 miles W. of Karachi Harbour, Pakistan, 25?15'N 63?30'E; sandy beach; 3 males (carapace length 13.00 13.25 mm), 6 ovigerous females (carapace length 11.50-14.00 mm). An ovigerous female, measuring 14 mm in carapace length, is selected the holo type and a male, with carapace length 13 mm, is the allotype. The entire collection is preserved in the Invertebrate Reference Museum Karachi University. Description of the holotype. ? The rostro-gastric shield (i.e., the dorsomedian area before the cervical groove), measured from the anterior tip to the cervical groove, is slightly more than two-thirds of the total carapace length. It is twice as long as its maximum breadth and the tip is broadly rounded (fig. 1 A, B). The rostro-gastric shield reaches to about the middle of the penultimate segment of the antennal peduncle. The rostrum is half as long as broad and on the anterior margin is armed with four acute upstanding spines arranged as a crescent and placed some what behind the margin, their tips are curved posteriorly (fig. 1 B, C). The lateral frontal teeth are placed farther backward, they are strong, spine-like and directed obliquely upwards. Behind each tooth there is a longitudinal carina bearing a row of tubercles, which become smaller posteriorly; there are altogether eleven tubercles on the right and twelve on the left carina. The longitudinal carina is separated from the median post-rostral region by a groove, which disappears posteriorly. The tubercles on the anterior surface of the rostro-gastric shield are larger and more spine-like than the posterior tubercles, which become small and rounded. It may
